DELIVERY DEVICE.

Application filed July 31, 1913. Serial No. 782,168.

To all lwhom it may concern:

Be it known that I, ALBERT B. DICK, a citizen of the United States, residing at Lake Forest, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in Delivery Devices, of which the following is a specification.

This invention relates lto'delivery devices for use with printing and folding machlnes for receiving the sheets of paper after they have passed through the machine and stackin'g them so that they may be conveniently handled thereafter. l l

The invention is directed to the provision of an improved form of delivery dev ice which is inexpensive to manufacture, which is convenient to operate, which is readily adjustable for use with sheets of varying sizes and which is specially useful in connection with small printing machines such as stencil du licating machines.

ne feature of the invention resides in the provision of a guiding device for gulding the sheets delivered by the machine downwardly upon a pile in the delivery tray. T his consists of one or more arms pivotally mounted above the sheet-pile and extendmg downwardly at an angle to a point adjacent to the edge of the sheets in the tray distant from the machine. The arm or arms thus arranged guide the sheets so that they move to the proper position in the tray and because of its pivotal mounting, the arm will rise as the thickness of the pile increases. Preferably the arm extends beyond the edge of the pile so that it willvnot contact with ithe ink on the sheets, as by extending it so that it projects through a slot in the end wall of the delivery tray. The tray is made largely of sheet-metal parts so that it may be manufactured at low cost, the construction being such as to facilitate manufacture from sheet-metal. These parts are so shaped and arranged as to permit adjustment of the length of the tray and the distance between the side-guides thereof.

The preferred embodiment of the invention is illustrated in the accompanying drawings in which- Figure 1 is a central longitudinal section through the device showinga printing machine diagrammatically, Fig. 2 is a view of a portion of the bottom of the tray, Fig. 3 is a plan view of the delivery devlce, Fig.

4 is a transverse section of the delivery device and Fig. 5 is a view of the bottom of a portion of the tray showing one of the side-guides.

Referring to these drawings, a stencilduplicating machine is illustrated diagrammatically in Fig. 1, this being typical of any form of apparatus adapted to operate upon sheets successively. This machine has a base ,6, side-frames 7 mounted thereon, a drum-8,

the edge thereof distant from the rod 10.

This upright portion or wall 12 is adapted to arrest the movement of the sheets into the tray. A sheet-metal strip 13 is providedA having projections 14 at one end as shown in Figs. 1 and 3 for coaction with rod 10. Strip 18 is also provided with two depressed portions 15 of less width than the strip formed by making two parallel lengthwise cuts in strip 13 and depressing the metal between these cuts. The strip so formed is laid upon the upper surface of the botto-m of the tray 11 with the depressed portions 15 projecting through a slot 16 in the base 11 of the tray. Flat sheet-metal springs 17 are then positioned over the depressed portions 15 and under the base 11'of the tray. Each of these flat springs 17 is secured at the middle portion thereof to the underlying depressed portion 15 and its ends bear upon the under surface of the base 11 ofthe tray. By this construction it will be seen that the two parts 11 and 13 of t-he delivery device may be readily moved relatively so as to increase or decrease the distance of the upright wall 12 from the rod 10, this capacity for adjustment being desirable in order to adapt the delivery device for receiving sheets of different lengths.

The tray above described is provided with side-guides for coaction with the side edges of the sheets and these side-guides are relatively adjustable. For this purpose, the bottom 11 of the tray is provided with two transverse slots 18 and each of these slots has a plurality of notches in one of the walls thereof as shown at 19. Each side-guide consists of a sheet-metal piece bent to form a base portion 2O and an upright portion 21. rl`he base portion 20 bears upon the upper surface of the base 11 of the tray. To the under side of the base portion 20 is secured a sheet-metal piece 22 of a size to lit within the slot 18 and move therein lengthwise of the slot. Each piece 22 is provided with a projection 23 adapted to enter any one of the notches 19. The piece 22 is preferably of the same thickness as the base 11 of the tray. 'lo the under side of this piece 22 is secured a flat spring 24, it being fastened to the iece 22 intermediate its ends and having its ends bearing upon the under side of the base 11 of the tray. This iiat spring 24 is displaced from the projection 28 in the direction of the length of the slot 18.

With the side-guides in the position shown in Fig. 3 it will be seen that they are held from movement toward and away from each other by the projections 23 coasting with the notches 19. Fach side-guide is held in the position shown with its base 20 flat against the base 11 of the tray and its projection 23 in the notch 19 by its spring 24. lf it be desired to move a side-guide, it is only necessary7 to grasp the upright portion 21 thereof and move it laterally slightly thus rocking the side-guide as a whole against the tension of its spring 2a until the projection 23 is out of the slot 19. The side-guide may then be moved bodily in the direction of the length of slot 18. @n releasing the guide, the spring 2d will cause it to assume its upright position and the projection 23 will again enter a notch 19 so as to again hold the guide from lateral movement.

A gravity-actuated member 25 is provided to coact with the sheets as they are moved into the tray and cause them to move in the desired manner. This member 25 is carried by a support 26 in the form of a bail made of wire. This support 26 is pivotally mounted upon the upright portion 12 of the tray. This wall of the tray has ears 27 thereon upon which members 28 are pivoted and the ends of bail 26 are secured to these members 28. The members 28 have projections 29 thereon which coact with the wall 12 of the tray to arrest turning movement of bail 26 when the latter is in an upright position. When the bail 26 has been turned to the position in which it is shown, its movement is arrested by the wall 12. rlhe member 25 is pivotally mounted upon bail 26 at the bight of the bail and is adapted to turn freely on a horizontal axis. rlhe member 25 is preferably formed from a piece of wire whose end is coiled around the support 26. A sheet-metal piece 30 is secured to the support 26 and provided with a slot through which the wire 25 extends, this wirt serving to limit the turning movement of the wire 25 on the bail 26. rlfhe wall .12 of the tray is provided with a slot as shown at 31 to receive the free end of the wire 25 in which slot this end of the wire is vertically movable.

With the parts in the position shown in Fig. 1, sheets of paper forwarded into the tray engage the. wire 25 and are guided thereby downwardly upon the Pile. The mounting of the member 25 permits the same to yield so that its free end moves upwardly as the thickness of the pile increases. Also the end of the member 25 does not contact with the printing upon the sheets at this end coacts with the edge of the sheet distant from the printing machine with the eXtreme end projection through a slot in the end wall of the delivery tray. When it is desired to remove the pile from the tray, the bail 26 is turned about its pivot to an upright position carrying the member 25 with it so that the bail and member are out of the way when removing the pile of sheets.

From the foregoing description, it will be noted that the delivery device herein illustrated is one of simple construction permitting of manufacture at very low cost and specially adaptable for use with stencil-duplicating machines. lt may be readily attached to and detached from the machine and it may be readily adjusted for paper of a different length or diderent width. When the proper adjustment has been made, the parts will remain in the new position held there by the springs employed.
